MACHINE FOR MANUFACTURING BOTTLE-COVERS.

SPECEPICATION forming part of Letters Patent No. 336,097, dated February 16, 1886.

Application filed August 20, 1885. Serial No. 174,920. (X0 model.)

To all whom it may concern:

Be it known that I, THEODORE A. DODGE, of Brookline, county of Norfolk, and State of Massachusetts, have invented an Improvement in Machines for Manufacturing Bottle-Covers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a machine by which to manufacture bottle-covers from paper.

My invention consists, essentially, in the combination, with a guide to fold a strip of material into tubular form, and stitch-forming mechanism to unite the said tube, of feeding and cutting mechanism to feed the said tube and to out it into lengths suitable for covers.

Figure 1 is an elevation of a machine em bodying my invention; Fig. 2, in vertical crosssection, shows the cutting mechanism which I have added to the stitch-forming mechanism, and also a horizontal section of the said rolls in the dotted line as w,- and Fig. 3 shows abottle-cover complete.

Referring to the drawings, the bed-plate a, the main-shaft c, the head i, the cams t and w, the lever 11, the link if, the pawl-lever 8 the pawl t the shafts c 19 their attaching feeding-rolls g r, the lever e*, the link (1 the shaft 1), the arm a for actuating the rack-bar to oscillate the usual whirl (not shown,) the worksupporting arm 9*, partially surrounded by the long grooved guide if, the latter lapping or folding the material in tubular form about the frame g the presser bar 8 and presserfoot Z, the needle-bar 7;, the hooked-needle m, the cast-off bar n, and the cast-off j are all substantially as in the United States Patent No. 146,948, granted January 28, 1874, to E. P. Richardson, to which patent reference may be had, the said mechanism being herein employed to stitch or unite paper to form tubes to be made into bottle-covers. The feedingrolls (12 r draw the material from the stitching mechanism and pass it in tubular form between the cutting mechanism herein shown, as cylinders A B, the former provided with a transverse cutting-blade, A, and the latter with a transverse slot, B the said cutting mechanism, as herein shown, flattening the tube T and severing the same transversely,

the circumference of the said rolls being substantially equal to the length of the bottlecover to be made. The shaft of the cylinder B has fast upon it the gear B, which is engaged and rotated by the intermediate B, which derives its motion from the toothed gear rflcommon to said patent, and fast on the shaft 19. The shaft of the cylinder A is retated by the gear B, which engages the gear 138, so that the two cylinders move in unison, the surface-speed of the said cylinders and of the rolls g 1" being the same. The cylinder A, is provided with two cutting-blades, D, at right angles to the blade A, (see Fig. 2,) which blades enter grooves B at right angles to but intersecting the groove B, the said blades 1) cutting longitudinal slots 2 2 at one end of the bottle-cover tube T to enable that end of the tube to be closed squarely.

Referring to Fig. 3, the stitch uniting the paper into atube is shown at 4; but instead of the chain-stitch mechanism of the machine herein shown I might employ any other wellknown stitch-forming mechanism in connec tion with a folding-guide arranged in front thereof and with a tube feeding and cutting mechanism arranged rearward thereof. The material to be used for the manufacture of bottle-covers will preferably be thick paper, embossed or indented at intervals so as to form projections and leave depressions to give softness and elasticity to the paper. The paper used will be formed into a tube by passing the same between the guide h andthe arm g, as described in the said patent, the paper strip introduced in flat or nearly flat condition being folded into tubular form with its edges overlapped, as or before it arrives in position under the bar It, to be united by the stitch or fastening used.

Having described a mechanism by which to practice my invention, I desire it to be understood that instead of the particular stitchforming mechanism shown, I mayemploy any other stitch-forming mechanism commonly used for stitching hose or tubing; and instead of the particular cutting mechanism which is common to machines for forming paper bags and for cutting off paper tubes, I may use any other mechanism commonly employed in paper-bag machines by which to sever paper tubes into bag lengths, it being possible to employ such other devices by but slight changes in mechanical devices to operate the cutting-off mechanism in the proper time with relation to the stitching mechanism.

I claim- 1. A guide to fold a strip of paper or other material into a tube and stitch-forming mechanism to unite the said material to form a tube, combined with tube-feeding and tubecutting mechanism by which to feed the said tube and cut it into short lengths, the said guide being arranged in front of the said stitch-forming mechanism, and the said feeding and cutting mechanism rearward thereof, substantially as described.
